I've had her book for ages, but started to re-read the other day after Hv suggesting mag malate. I don't think i read it properly the first time around.
I was put off magnesium, after i suspected i unbalanced my cal/mag ratio, because i got leg pains, and cramp. That was the citrate and the taurate, i'm now taking the malate. I'm still a little wary, but not taking as much as last time.
